Kitchen Finks ? generic? Sure.. Good? You bet...

I would consider some red miracle effect spells. After all, only Bloodbraid Elf has cascade.

For a run-of-the-mill jund deck, this features very few lands and very few man lands..

Also why no Blightning ?

@mattil - uhmm.. actually, this is a Gruul deck as the description says.. I don't plan on making this a Jund by any means.. that is why there is no Blightning .. The man lands are enough, 2 tapped lands that can be a 3/3 trample ape for 1G, is better than Raging Ravine since this is a fast deck, having to kill on 3 to 6 turns..

Kitchen Finks is good sideboard card.. but with most burn decks that I have faced, I often out-burn them.. and I just don't know where to put it in my sideboard..

maybe Bonfire of the Damned is good, but I want to really play test it first, before buying.. since it is quite expensive..

Huntmaster of the Fells  ^Flip Branching Bolt maybe?

@Sidneyious - actually, ErickLim already suggested Huntmaster of the Fells  ^Flip .. the thing that I want with him is that when he comes into the field, opponent has two separate creatures to worry about, unlike Vengevine .. but I feel that vengevine is a better pick among the two.. Maybe I could add a few..

Branching Bolt could be a sideboard to replace Incinerate .. but is Pyroclasm a better mass removal? Arc Trail is a different type of branching bolt.. which i think is better, because it can blast the opponent directly.. thanks for the suggestions btw..

Kessig Wolf Run , might be useful?

@m12fox - i'll test if it could work, maybe i could add one or two.. thanks!

Why not add a couple of Banefire s? for late game finishes?

@SethArg - hmm.. good idea! plus it can't be countered.. i'll test it to be sure.. thanks!
